In Windows Terminal, how do I add bash as one of the shell options?

I’m using Windows 10 and just downloaded and installed the latest version of Windows Terminal. I would like to use a bash shell within the terminal but when I open the settings, I don’t see bash as an option

Is it possible to add bash (or something like it) as a selectable shell and if so, how do I do it?
